Carbon　nanoflakes　(CNFLs)　are　synthesized　on　silicon　substrates　deposited　with　carbon　islands　in　a　methane　environment　using　hot　filament　chemical　vapor　deposition.　The　structure　and　composition　of　the　CNFLs　are　studied　using　field　emission　scanning　electron　microscopy,　high-resolution　transmission　electron　microscopy,　micro-Raman　spectroscopy,　and　X-ray　photoelectron　spectroscopy.　The　results　indicate　that　the　CNFLs　are　composed　of　multilayer　graphitic　sheets　and　the　area　and　thickness　of　CNFs　increase　with　the　growth　time.　The　photoluminescence　(PL)　of　CNFLs　excited　by　a　325　nm　He-Cd　laser　exhibits　three　strong　bands　centered　at　408,　526,　and　699　nm,　which　are　related　to　the　chemical　radicals　terminated　on　the　CNFLs　and　the　associated　interband　transitions.　The　PL　results　indicate　that　the　CNFLs　are　promising　as　an　advanced　nano-carbon　material　capable　of　generating　white　light　emission.　These　outcomes　are　significant　to　control　the　electronic　structure　of　CNFLs　and　contribute　to　the　development　of　next-generation　solid-state　white　light　emission　devices.
